It might help if you specified which version of U-Boot you run and for 
which board it is built.

Note that if you're not using the mainline U-Boot but a custom vendor 
one, you should inquire with the vendor.

Note also that if you're using the mainline U-Boot, then you should make 
sure you're using the latest version.
